Hi,
I have had my implant for very nearly 3 years now and have had really sore boobs for the past week! They haven't really hurt before and i'm now getting slightly concerned that the implant has become less effective and i could be pregnant. My periods have been messed up since being on this so can't really tell if i'm late. The implant is due to be replaced in 1 month.
Does anybody have any experience on whether the chances of the implant failing are higher towards the end of the 3 years, or if this might just be a normal hormonal thing?
Thank you
